AGILE 5250 OPTIMA User’s Guide and Reference

 

 

Command:

Load Alternate Characters (LAC)

Format:

2B FE nn mm ch i1 i2 i3 i4 i5 i6 i7 i8 i9 [i10]...

Printers:

4214, 5224, 5225

Action:

Specifies new character bit images for selected

 

characters. The parameters ch and i1 through i9 (or i10)

 

must be specified in sets (10 or 11 bytes per set).

 

The mm parameter specifies the image type for all

 

character images defined with the command.

 

For the 4214, valid values for the mm parameter are 01h,

 

which specifies that the bit images are 8 bits tall by 9 bits

 

wide, and 02h, which specifies that the bit images are 8

 

bits tall by 10 bits wide.

 

For the 5224 and 5225, the only valid value is 01h.

 

The ch parameter specifies the character for which a new

 

bit image is to be defined. The ch parameter value may

 

range from 00h to FFh. Control characters that have bit

 

images defined for them in this way may be printed in

 

transparent mode. See Transparent (TRN 35h) for more

 

information.

 

Parameters i1 through i9 (or i10) are the bytes of image

 

data. The data is organized as vertical “slices” of eight

 

bits (one byte) each. For 8 x 9 mode (mm=01h), there are

 

9 bytes of slice data per character bit image. For 8 x 10

 

mode (mm=02h) there are 10 bytes of slice data per

 

character bit image.

 

The first byte of bit image data for a character is the

 

leftmost vertical slice of the character bit image; the last

 

byte of data is the rightmost vertical slice of data.

 

The most significant bit of each byte is the top bit of the

 

slice; the least significant bit of each byte is the bottom

 

bit of the slice.

 

Bits that are set ON are printed as black; bits that are set

 

OFF are not printed.
